The Horde Application Framework is a modular, general-purpose Web application framework. It provides an extensive array of classes that are targeted at the common problems and tasks involved in developing modern Web applications.

PHP MIME Mail decoder class is a PHP class to parse and decode MIME email messages. It supports decoding single RFC 2822 MIME messages or archives that aggregate multiple messages in the mbox format. It can decode messages read from files or data strings. The bodies of multipart messages can be decoded into distinct sub-messages. Optionally, the message body data can be saved to separate files, so the class can handle messages larger than the available memory. The parser can tolerate some syntax errors in malformed messages that are not compliant with RFC 2822.

PSX is a PHP framework for creating RESTful APIs. It helps you to build clean URLs serving Web standard formats like JSON, XML, Atom, and RSS. It includes a handler system that abstracts away SQL queries from domain logic, a routing system that executes correct controller method for the location of the controller and the method annotation, and a flexible data system that converts database records into formats like JSON, XML, Atom, and RSS. A lightweight DI container handles dependencies. The controller supports request and response filters that can modify the HTTP request or response, and filters are provided for Basic and Oauth authentication.

This is a PHP class that attempts to validate a given e-mail address at four levels: matching the address against a RFC compliant regular expression; checking whitelists and blacklists of domains with typing mistakes, disposable email addresses, and temporary and fake domains; verifying the existence of the destination SMTP server by verifying the respective DNS MX record; and connecting to that server to see if the given address is accepted as a valid recipient. The class also features a debugging output option that lets you see the remote SMTP server connection and data exchange dialog to see the real cause why an apparently valid address may not be accepting messages.

OpenTBS is a PHP tool that helps you to make OpenOffice and MS Office documents using templates. You first design your template using OpenOffice or MS Office, and then OpenTBS merges it with data that you supply from PHP code and databases. It has facilities to manage pictures. The resulting documents are saved to file, served for download, or returned as a string. In fact, OpenTBS can merge any OpenDocument files, any OpenXML files, and any XML files compressed in a Zip archive. No extra exe file is required and it makes no temporary files, since all work is done in memory. OpenTBS is based on the TinyButStrong template engine.

more secure, HTML standards-compliant, and

HTML 4 or XHTML 1 or 1.1 documents. It is a
customizable HTML/XHTML filter, processor,
purifier, and sanitizer. It can ensure that HTML
tags are balanced and properly nested tags,
